Qelectrotech Portable

Configuring the "proper paper" size in QElectroTech (QET) Portable is essential for ensuring your electrical diagrams print and export without distortion or cut-offs. Because QET uses a pixel-based grid rather than physical units by default, you must align your Folio properties with standard paper dimensions. 1. Match Pixels to Paper Size

To ensure your workspace matches the paper you intend to print on, use the following pixel dimensions for a standard 96 DPI (dots per inch) resolution: Paper Size Dimensions (mm) Pixels (Width x Height) Recommended Columns/Rows A4 (Standard) 794 x 1122 px 17 columns x 8 rows 1122 x 1587 px 22 columns x 11 rows Letter (US) 215.9 x 279.4 816 x 1055 px 10 cols (105px) x 5 rows (163px) 2. How to Change Folio Size

: Right-click on your folio (the drawing page) in the project tree and select Folio properties Adjust Dimensions : Go to the Dimensions Columns & Rows

You must manually set the number of columns and rows and their individual pixel sizes (e.g., for 17 columns Apply to Project : To make this the default for all future pages, go to Project Properties 3.
